hey guys i need a bit help. So, i bought the game and i can run it with no problems. BUT It lags as crazy. no metter how much i lower the graphic. i can run Saints Row the third perfectly (full graphic, no lag at all), Skyrim, CoD 8, Battlefield 3, all on full graphic... Why does this game lag so much? any fix? thanks! ^^

First of all, what hardware do you have?

Second of all, did you go through the FAQ and the performance section and follow everything exactly?
